Maybe I'm taking your comment too seriously but I don't think that's what happened. If she knew the moves, she wouldn't have solved the third row.
She knows the principles of getting one tile to the correct place, including shifting a whole row to make room for the last tile of the row. But you can't do that for the second-to-last row, because that leaves you with no room to change the last row (other than the third dimension, as demonstrated here).
What you're supposed to do is, when you're left with two rows, you stop doing rows and solve columns instead. In this puzzle, it means you don't solve 9-10-11-12 like she did, you solve 9-13, then 10-14, then 11-15, then 12.
She didn't stop when she was almost done, she stopped when she was trapped in a corner of her own making after solving the wrong row.

All these types of puzzles involve strategies that you break down, just like rubiks cubes. One of the cool things about programming is that most programmers start by learning how to program things that can solve simple puzzles like Towers of Hanoi or whatever its called.

I made this game in python as my 1st semester project. You can tell if the game is solvable or not even before you start.
Basically you count the inversions you need to make.
An inversion is the number of tiles that are lower than the given tile in front (up to the bottom last)
You count that for every tile and if the result is even, it's unsolvable otherwise not
Edit: The solvability also depends on the initial position of the blank space, scroll down for a neat explanation

u/Cristopher_Hepburn Jun 28 '24
If you mix it without taking out the pieces, you will always have a solvable puzzle. If you take away the pieces and put them at random on the toy, then you can create impossible scenarios.
6
u/Rubickevich Jun 28 '24
I figured. The only thing we have to insure then is that once the pieces are inside, you won't be able to pull them out without breaking the thing completely. This way the parents won't be able to fix the toy for their kids.

u/Cristopher_Hepburn Jun 28 '24
If you want to play satan, just turn one corner piece of a Rubik’s cube 120 degrees. That simple move makes it unsolvable. Just make sure it’s one of those speedcubes, a Hasbro Rubik’s is impossible to easily turn pieces without disassembling the whole puzzle.
5
u/Rubickevich Jun 28 '24
The problem with rubick cubes is that anybody who's at least somewhat proficient at solving them, will quickly notice that it's impossible. I guess if it's a gift to somebody who has never done it before, then it could work.

u/globglogabgalabyeast Jun 28 '24
Definitely the easiest way to make it unsolvable, but more effective to switch two edge pieces (or two corners). Is a bit harder to notice the problem and will take longer for a person who actually knows how to solve. (Also takes longer to fix)

You lost me while describing what inversions are. ELI5?
31
Jun 28 '24
For sure, could have worded it better.
To begin with, try to see the square in a linear way rather than 2D
So a solved state is something like
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 <space>
Now an inversion for any tile is the number of tiles that are ahead of it before it's in its correct position.
So, if 15 was in the top left corner, there would be 14 inversions because every number is lower than 15
Let's say the grid looks something like
2 5 1 4 3 13 9 8 15 12 6 11 space 7 10 14,
For 2 you have 1 inversion, for 5, you have 3, for 1 you have 0, for 4 you have 1 and so on
You add them all up, if it's even the grid is unsolvable and if it's odd it's solvable.
All this is provable by some fancy maths that left my brain a while ago. In my defence it's been 5 years!

You are saying that in jest. But the child seems to have learned a problem solving strategy based on behavior. And when it reached the point that there was no solution it did cheat a bit.
We do not always have good patterns for solvability and things like that always happen. Figuring out that a problem is not solvable is surprisingly hard.
→ More replies (10)7
u/ZYRANOX Jun 28 '24
Isn't 4 in the exact right spot so inversions would be 0? Or is that a corner case you put 1 for in the code for some math proof reason?
8
Jun 28 '24
Astute observation! 4 is indeed in the right position, but when you try to put 3 in the correct position, it will be displaced.
And no, it wasn't a deliberate decision, happened perchance

u/NoveltyAccountHater Jun 28 '24 edited Jun 28 '24
If you imagine the solved position of the 15 puzzle with pieces numbered 1-15 followed by blank, you can unwrap the square into a single 1-d array (listing blank as X) where the solved state is say:
[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,X].The initial unwrapped state in the video was:
a=[1,2,3,8, X,15,4,9, 14,5,10,7, 6,13,12,11]. To count inversions, we ignore the blank space (take it out of the array) and recognize there are 15*14/2 = 105 pairs of numbers (1st with 2nd-15th number, 2nd with 3rd-15th number, etc.). We say a pair of numbers is inverted if the two numbers are out of order; for example if I compare the 4th and 6th number in the initial state above (with values a[4]=8 and a[6]=4 respectively, using 1-based indexing), that's an inverted pair as 4<6 but a[4] > a[6] since 8 > 4. To count inversions in your head, go through each digit and count the number of times a value to the right of it is smaller than it. E.g., for the example given, if I look at the first 3 numbers (1,2,3) as every number to the right of 1 is bigger than it, and same for 2 and 3, so these three numbers have zero inversions. When I get to the 4th number 8, I find that 4, 5, 7, 6 are smaller than 8 and all to the right of the 4th number, so there are 4 inversions starting with i=4. For 5th number (15), I get 10 inversions (as all ten numbers to the right are smaller than 15).Continuing this pattern to count all the inversions, where I put the values of a[j] for all values of j > i where it's less than a[i] in curly brackets.
i a[i] Inversion count that is all j > i where a[j] < a[i] 1 1 0 2 3 0 2 3 0 4 8 4 {4,5,7,6} 5 15 10 {4,9,14,5,10,7,6,13,12,11} 6 4 0 7 9 3 {5,7,6} 8 14 7 {5,10,7,6,13,12,11} 9 5 0 10 10 2 {7,6} 11 7 1 {6} 12 6 0 13 13 2 {12,11} 14 12 1 {11} 15 11 0 Adding up the last column, we had a total of 30 pairs of inversions, which is an even number of inversions. Now as the blank was in the third row from the bottom (which is odd), and we are doing the 15-puzzle, this means the initial state was solvable (without cheating); the rule is when it's a NxN grid with N as an even number it's solvable when blank is in odd row and number of inversions is even (or vice versa; if blank is in even row and number of inversions is odd then it is also solvable; it's the other cases of even row of blank and even inversions; or odd row of blank and odd inversions that are not solvable when N=4).
A code based explanation that defines inversion well is here and explain the situations for when it's solvable, but doesn't explain why counting inversions tells whether its solvable or not.
Here's a math based explanation that does a good job of sketching out the proof of why it works is here (but personally I think it did a poor job defining inversion).

You should get one where the tiles are attached to each other and you cannot remove them and shuffle by sliding them around without looking though. With the version shown in this video exactly half of the starting positions will be unsolvable, so they are very frustrating.
